The index of refraction of a type of glass is 1.50, and the index of refraction of water is 1.33. If light enters water from this glass, the angle of refraction will be
A) equal to the angle of incidence.
B) greater than the angle of incidence.
C) less than the angle of incidence.

When light travels from a medium with a higher index of refraction (glass, 1.50) to a medium with a lower index of refraction (water, 1.33), it bends away from the normal. This means the angle of refraction is greater than the angle of incidence, according to Snell's Law.
